Lightweight and with a simple design, the Tusa Freedom Tri-Quest Dive Mask gives you a clear view of the world around you with minimal interference. The large lens at the front of the Tusa Freedom Tri-Quest single lens dive mask gives you a broad field of view with truer colors and clarity, with the CrystalView Optical Glass it’s made from. The low-profile frame design minimizes blind spots, and domed windows at either side extend visibility even further for an even more immersive experience underwater. Around back, there is a 3D Strap that is pre-curved to better fit on your head, while the Freedom Technology Skirt is dimpled to improve the watertight seal without adding stiffness or discomfort.
